There are 2000 mice living in a field. If 1000 mice are born each month and 200 mice die each month, what is the percentage growth rate of mice over a month? Correct Answer 40

Given:

2000 mice living in a field and 1000 mice born and 200 mice die each month.

Formula used:

Percentage = {(change in population)/population} × 100

Calculation:

1000 mice born each month.

And 200 die each month

That means 1000 – 200 = 800 mice

Change in population is 800 mice

Growth% = (800/2000) × 100 = 40%

∴ Growth percentage is 40%.

In each question below is given a statement numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the following assumption and decide which of the assumption is implicit in the statement. Statement: The June 2018 quarter results of Infosys reflect that the investors waiting for the company to perform as good, if not better, than its largest peer Tata Consultancy Services (TCS) may have to wait a little longer. Infosys, the country’s second-largest software exporter reported slower sequential growth in revenue and profit than TCS for the June quarter (Q1). It also lagged on the fronts of employee attrition and growth in the banking, financial services, and insurance (BFSI) vertical.  Assumptions: I. On the positive side, Infosys continued to add large clients – four in the above $100-million billing category compared with the previous quarter. It continued to retain guidance of 6-8% revenue growth for FY19 while retaining the operating margin band of 22-24%. II. In the near term, the stock performance of TCS is likely to overshadow Infosys given the difference in their growth trajectories. III. The growth momentum of Infosys has slowed relative to TCS. The year-on-year growth in trailing 12-month (TTM) revenue of Infosys in each of the four quarters up to the June 2018 quarter has lagged TCS after leading in the previous five quarters.
